ABSTRACT: Recent advances in wireless technologies have enabled pervasive connectivity to Internet scale systems which include heterogeneous mobile devices, such as mobile phones and personal digital assistants, a trend which is generally referred to as ubiquitous computing. This leads to the need for providing security functions to applications which are partially deployed over wireless devices. Delivering security services to mobile devices raises a number of challenging issues, mostly related to the limited amount of computing power which is typically available on the target plat-forms. Some promising solutions rely on multi-tier architectures, which are based on the emerging Web services technology. In this scenario, understanding the impact of architectural characteristics of specific platforms is a key issue for practitioners who have to develop and deploy efficient security-enabled applications on mobile devices. This paper provides an experimental study of the impact that specific characteristics of individual mobile device platforms have on the final performance of security applications. Focus is on performance and resource utilization, which are key aspects when one develops applications on mobile devices. The case study is a Web services based solution for delivering public key infrastructure (PKI) services to mobile devices. Experiments have been conducted on three different mobile terminals, which span a large range of characteristics in the class of resource-constrained devices. Results show that: i) performance figures are not uniform in spite of similar underlying hardware characteristics, and ii) security and performance are often conflicting requirements

ABSTRACT: Information security is a key requirement in emerging networked scenarios, which typically involve a large variety of heterogeneous, often resource-constrained devices. Providing security to this emerging class of distributed applications raises a number of new challenges. This paper discusses such challenges with respect to two key security services, namely public key certification and digital timestamping, and presents a multi-tier architecture which combines a hardware-accelerated back-end and a Web Services based Web tier to for achieving interoperability while boosting performance. The paper describes the organization of the multi-tier architecture, provides a detailed description of individual components, and presents the results of a thorough experimental campaign

ABSTRACT: Cooperative services in Service Oriented Architectures (SOA) inter act and delegate jobs to each other; when they have to
respect a Service Level Agreement (SLA) they need to explicitly manage it amongst each other. SLAs and, above all, security-SLAs,
are usually expressed in ambiguous ways and this implies that they need to be manually evaluated both in a mutual agreement
to ”qualify a service” and in the monitoring process. Due to this approach, usually, service composition cannot be dynamically
performed. In this paper we introduce a methodology which helps in security SLA automatic evaluation and comparison. The methodology
founds on the adoption of policies both for service behav ior and SLA description and on the definition of a metric function
for evaluation and comparison of policies. We will illustrate the applicability of the proposed methodology in different contexts
of great interest for e-government projects.
